The performance of a diagnostic examination1 can be basically considered as its degree of accuracy, namely its ability to find the subjects affected with a given disease as positive and the subjects not affected with same disease as negative. The indices which in different ways measure this performance are defined measures of diagnostic performance and the studies aimed at measuring the diagnostic performance of an examination or, more often, at comparing the diagnostic performance of two or more examinations, are defined studies of diagnostic performance.
